Zed

Zed Language

Zed is a language consisting of a total of 32 distinct symbols. A program consists of commands, as well as nested loops, scopes, threads, variables, and functions. Each scope has a single stack of which infinite signed long numbers may be added to. A memory value is also present. Labels may be used for definitions or calls.

Symbol	Action
+	Increment Memory By 1
-	Decrement Memory By 1
?	Pop From Stack
!	Push To Stack
%	Get Stack Size
.	Output Unicode Character
,	Input Unicode Character
:	Restart Execution
;	Complete Execution
*	Delay Milliseconds
<	Initiate New Thread
>	End Thread
(	Repeat Equal to Value or Variable
)	End Repeat or Variable
[	Repeat Until 0 or Function
]	End Repeat or Function
{	New Scope Block
}	End Scope Block
#	Export Memory To Child Scope
&	Import Memory From Parent Scope
/	Max Long Value
\	Reset Memory Value
=	Modify Execution Position
"	Get Execution Position
'	Set Execution Position
~	Opposite of Value
`	Exit Program
$	Toggle Debug Mode
@	Get Scope Depth
|	Get Milliseconds Since
^	Access Parent Scope
_	Access Child Scope

Variables, scopes, and threads are computed immediately. Functions are saved. A function call runs that bit on the current scope. A scope call becomes the current scope. Variable calls replace the value. This language is a work in progress, but here are some of the very programs that work on the fully functional Java interpreter.
